This invention relates to an improvement in a sash window and moreparticularly to one which may be manipulated to facilitate cleaning orto change or control ventilation.

The preferred embodiment of the invention discloses a unitary structurewhich may be mounted in a window opening and which consists of a frame,guides and sash.

The principal object of the invention lies in the provision of a windowstructure having an insertable or removable frame in which is mounted' asliding sash.

Another object of the invention lies in the provision of a windowconstruction, the sash of which may be. swung inwardly for the purposeof facilitating cleaning.

-A further object of the invention lies in the provision of a devicecomprising a sash and guide frame which may be assembled by themanufacturer and installed as a unit in a window open- Another andfurther object of the invention lies in the provision of a structure ofthis kind which is easily manufactured and installed and which, as aresult, is economical to produce.

Other and further objects of the invention may be more clearlyunderstood from a consideration of the following specification which istaken in conjunction with the accompanying drawings, and in which Fig. 1is a front elevation of one modification of this invention in positionof use;

Fig. 7 is a horizontal sectional view, similar to Figure 2, showing aslight modification of the structure of that figure.

' Referring to the drawings, one modification of the invention is shownmounted in a window opening, the walls of which are generally indiasdesired, or may be formed from wood or, 6

in fact, any convenient material. The vertical walls of the windowopening are fitted with rails 16 which, through inner and outer flanges1'7 and 18, are secured to the Wall. Connecting these flanges is aninner straight portion 19 having an inwardly projecting rib 21. The rib,along the inner face 22 in the present showing, is formed with a slightrecess 23, the purpose of which willhereinafter be set forth. Formed inthe lower ends of the portions 19, commencing adjacent the covering 12and rib 21 are slots-24 which curve upwardly and inwardly and terminatein enlarged offset openings 25. The slots 24 are for the purpose ofmounting a removable frame which supports the sash. The upper horizontalwalLwhich 7 defines the window opening, is fitted with a metal. or othersuitable plate 26. This plate is preferably identical with that of therails 16, being formed with an inwardly projecting rib 2'7, connectedwith an extended flat portion 28. Referring to Figure 3, it will benoted that the ribs 27 and 21 coincide to form a continuous rib aboutthree sides of the window opening.

The frame 39, comprised of rails 31 and stile 32 joined together to forma downwardly opening U-shaped member, supports and guides oneor moresashes. The rails 31 are each formed with inwardly projecting ribs 33which terminate in flanges 34 engageable with the inner flanges 17 ofthe rails 16. These ribs extend the full length of the rails 30 anddefine the inner longitudinal edge thereof. The outer longitudinal edgeof each of these rails terminates in a flange 36 which, when the frameis mounted in the window opening, lies in the recess 23 of the face 22.

Between the flange 36 and rib 33 is located a sash guide 37 whichconsists of a longitudinally extending outer portion 38 connected byflanges 39 which in turn are connected with flanges 40,

parallel with the face 38. Flanges 40 terminate in short flanges 41which are parallel with the flanges 39. The guide 37 is joined to therail 31 along the portion 33 in any suitable manner as by welding. Itwill be noted that the flanges 41 are not only spaced from the adjacentribs 21 and 33 but from the base wall of the rail 31 as well, thusforming pockets 43, access to which is had through openings 45. Thestile 32 of the frame. 30 is formed with a downwardly projected portion46 having flanges 4'7 and 48. 1 Flange 47 terminates in an offset flange50 which is engageable with the room face of portion 26. Adjacent thelower outer portions of the rails 31 are pins 51 which project intoslots 24 of the rails 16. These pins are fitted with enlarged heads 52which prevent disengagement of the pins from the slots. The pins 51 andheads 52 may only be withdrawn from the slots 24 when moved upwardlyinto the offset openings 25, which terminate the upper ends of the slots24.

Sashes 54 and 55 are mounted in the guides 37. Each sash is providedwith outwardly opening rails 56 which are reinforced by outwardlyopening channel members 57. The combined thickness of one wall of therail and one wall of the channel is approximately that of the spacebetween the fiange 41 and face 22 of the rib 21.

Attached to one side wall of the channel member 57 is a leaf spring 59which, when the sash is in place frictionally engages one of the flanges39 of the guide 37. Pressure of the spring against this fiange causesthe inner face of one wall of the channel member 5'7 to engage theopposite face of the flange 39. The upper stile 61 of the sash 54 opensoutwardly and is reinforced with a channel member 62. Similarly thebottom stile 63 of the lower sash 55 is reinforced with an outwardlyopening channel member 64. The lowermost stile 66 of the upper sash isformed by two interengaging elements 67 and 68, the element 67 having aflange 69 spaced from a flange '70 of the element 68 to provide a fullwidth horizontally extending recess '72. The upper stile '74 on thelower sash 55 p is provided with a recess '75 formed by spaced stripping78 is located between the flanges 69 and 40 77. The formation andlocation of the trim for securing the glass 80 is common practice,forming no part of this invention and will not, therefore, be described.

It will be noted that the upper stile 61, when the upper sash 54 is inclosed position, lies between the flanges 48 of the frame stile 46 andthe rib 2'? of the portion 26. Stile 63, when the lower sash 55 isclosed, rests adjacent the shoulder 13 of the covering 12, being cut tofit the sloped portion 14.

Adjacent the upper portion of the movable frame 30 and mounted in therib 33 is a locking structure which consists of a rotatable latch 81mounted on a pin 82. The pin is supported in the flanges of the rib 33and is arranged with one end projecting through the outermost flange.The exposed end of the pin is provided with an angularly shaped openingwith which a key may be engaged to rotate the latch 81. A tapered slot84 is formed in the rail 16 with which the latch 81 is engaged to lockthe movable frame 30 in position within the window opening.

In Figure '7 of the drawings, is shown a slight modification of thepreviously described guide 3'7. In this instance, the guide 86 is joinedto the central portion of the frame stile 31 in any suitable manner asby welding and is formed with flanges 8'7 and 88 which define recesses89. In these recesses are located the leaf springs 59. The principaldifference of this structure is in causing the springs of each sash toexert outward pressure, thus moving the adjacent stiles of the sashesinto close engagement. The disclosure of Figure 2 shows the sashes beingurged away from each other.

The assembly and installation of a device of this type is very easilyaccomplished. The window opening is lined, so to speak, with metal rails16, sill covering 12 and upper stile or portion 26. These four elementsare installed separately, being joined together and to the walls of theopening 10 in any expedient manner. The frame 30, guides 37 and sashes54 and 55 may be assembled at the factory and installed as a unit in thewindow opening. The installation is accomplished by moving the sasheswithin a frame to a position substantially as shown in Figure 4 of thedrawings, engaging the pins 51 with the slots 24 by projecting the heads52 of said pins through openings 25. The frame may now be moveddownwardly, pins 51 following the slots 24 until a point is reachedwhere the stile 32 of the frame will move into position beneath theportion 26 and the flange 49 of the frame engages a flange of theportion 26. A key may now be inserted into the rectangular opening 83 ofthe pin 82 and when rotated causes the latch 81 to engage the wedgeshaped slot 84. When both latches, one in each rail of the frame, areengaged with the rails 16 which define the window opening, the structureis complete and the sashes may be vertically reciprocated at will.

It is not uncommon to find a sliding sash having an arrangement whichpermits swinging inwardly to permit cleaning. It is unusual and novel,however, to arrange an upper and lower sash in a pivotal frame which,through the manipulation of one or more latches, may be swung inwardlyto permit cleaning of both upper and lower panes of glasssimultaneously. It will be noted that by means of this construction, itis possible to quickly install the window or remove it and also that theadjustability or removability in nowise affects the weather proofingfeatures which prevail when the sashes are in closed position.

While applicant has shown and described but two modifications of theinvention, he does not intend to be limited thereto since it is obviousto those skilled in the art that other modifications or adaptations maybe made without departing from the spirit and scope of the invention asdefined in the hereunto annexed claims.
